Caalami - Premier DMF: Xalka Muhiimka ah ee Warshadaha Kala Duwan
Goobaha Codsiga ee ugu Muhiimsan
DMF si weyn ayaa loogu isticmaalaa warshadaha dharka. Waxay u adeegtaa sidii dareere muhiim u ah soo saarista fiilooyinka macmalka ah, sida nayloonka iyo acrylic. Waxay ka caawisaa inay milmaan horusocodka polymer-ka, taasoo u oggolaanaysa xakamaynta saxda ah ee habka wareegga waxayna keentaa fiilooyin tayo sare leh oo leh xoog iyo isku midnimo aad u fiican. Rinjiyeynta dharka, DMF waxaa loo isticmaalaa in lagu hagaajiyo milmida midabyada, taasoo suurtogalinaysa midabaynta dharka oo hufan oo xitaa siman.
Warshadaha dawooyinka, DMF waxay door muhiim ah ka ciyaartaa. Waxaa si caadi ah loogu isticmaalaa sidii dareere iyo dhexdhexaad falgal ah oo ku saabsan isku-darka daawooyinka kala duwan iyo daawooyinka dhexdhexaadka ah. Awooddeeda ay ku milmi karto noocyo badan oo isku-dhafan oo dabiici ah ayaa ka dhigaysa doorasho ku habboon fududeynta falgallada kiimikada ee adag, taasoo gacan ka geysaneysa hagaajinta wax-soo-saarka iyo daahirnimada alaabada kama dambaysta ah. Shirkadaha dawooyinka waxay ku tiirsan yihiin tayada sare iyo joogteynta DMF-gayaga si loo hubiyo badbaadada iyo waxtarka daawooyinkooda.
Warshadaha elektaroonigga ah ayaa sidoo kale ka faa'iidaysta DMF-gayaga. Waxaa loo isticmaalaa soo saarista semiconductor-yada iyo qaybaha elektaroonigga ah. DMF waxaa loo adeegsadaa in lagu nadiifiyo oo lagu milmo agabka sawir-qaadista, iyadoo la hubinayo qaab-dhismeed sax ah iyo sawir-qaadis xallin sare leh oo ku saabsan soo saarista wareegyada isku dhafan. Isbeddelkeeda hooseeya iyo awoodda xallinta ee aadka u fiican ayaa ka dhigaya dareere aan lagama maarmaan u ah ilaalinta tayada iyo waxqabadka aaladaha elektaroonigga ah.
Intaa waxaa dheer, DMF waxaa loo isticmaalaa warshadaha maqaarka. Waxaa loo isticmaalaa farsamaynta maqaarka si loo hagaajiyo jilicsanaanta iyo dabacsanaanta. DMF waxay ka caawisaa milmida iyo ka saarista walxaha aan loo baahnayn ee maqaarka, iyadoo sidoo kale fududaynaysa gelinta rinjiyeyaasha iyo walxaha dhammaystirka, taasoo keenta in alaabada maqaarku ay yeeshaan tayo iyo muuqaal la xoojiyay.
